What is an electronic invoice?

An electronic invoice is an invoice that is transferred electronically from the supplier to the invoice recipient. An electronic invoice is imported and processed electronically in the invoice recipient’s accounts system. PDF attachments or attachments to emails cannot be imported electronically and are therefore not regarded as electronic invoices.

How do I start sending electronic invoices to UiO?

It is not necessary to enter into a formal agreement between the supplier and UiO. The supplier must have a system to enable them to send electronic invoices, and be connected to a message centre or access point which facilitates the exchange of electronic invoices. The supplier must validate the messages against the specifications.
